Definitions

  • the present invention relates to building materials and methods and, more particularly, to a lightweight soundproofing, insulation and fireproofing material and method.
  • asbestos fireproofing is very lightweight, it is simply not feasible in many instances to utilize present cementicious fireproofing materials such as the product sold under the trademark "Monokote” by W. R. Grace & Co. or a similar material sold by U.S. Mineral Company, both of which are very heavy and do not contain sound proofing qualities. Without question, many buildings which require re-fireproofing were not designed for the weight of cementicious fireproofing materials.
  • a 2.54 cm (one inch) thick coating of "MONOKOTE” applied to 9.29 m3 (100 square feet) weighs on the order of 56.63 Kg (125 lbs). This is in contrast to asbestos fireproofing which only weighs on the order of one-fourth that amount. For construction based on asbestos fireproofing, the additional weight of cementicious fireproofing cannot be safely supported.
  • cementicious fireproofing While weight is a factor in asbestos replacement, cementicious fireproofing also has other serious drawbacks. This is true, for instance, in new construction where muliple coats of cementicious fireproofing must be applied in order to achieve desired thicknesses thereby escalating labour costs in its application and the very significant weight of cementicious fireproofing requires the use of heavier structural columns and beams due to the additional weight of this material. As a result, the cost of construction is escalated by reason of the necessity of oversized structural support.
  • Cellulose fibre has been used in spray-on insulation and fireproofing, and boric acid has been added to the cellulose fibre to increase the fire resistance thereof.
  • the boric acid is, however, corrosive to metal and therefore disadvantageous when used in an insulation and fireproofing for metal buildings and, to eliminate the corrosive effect of the boric acid, other chemical agents must be used to buffer the acid.
  • such chemical agents are expensive which significantly increases the cost while contributing nothing to the soundproofing and insulating qualities of the product.
  • the present invention is directed to a lightweight soundproofing, insulation and fireproofing material.
  • the material comprises a dry composition having 60-80% by weight of an inorganic lightweight nonflammable fibrous material, 16.67-36.67% by weight of an organic lightweight normally-flammable fibrous material, and 3.33-10% by weight of a refracted clay material which reduces the flammability of the normally-flammable fibrous material.
  • the material also comprises a liquid adhesive including liquid sodium silicate with a ratio of silicon dioxide, commonly known as silica sand, to sodium oxide, commomly known as soda ash, that is greater than 3.22:1, the liquid adhesive being used with the dry composition at the rate of approximately 208.18 l (55 gallons) of liquid adhesive for each 135.9 Kg (300 lbs) of dry composition.
  • the liquid adhesive is adapted to retain the dry composition on a surface in a fireproof manner.
  • the non-flammable fibrous material includes mineral wool and the normally-flammable fibrous material includes cellulose fibre.
  • Shredded paper is preferably utilized to provide the cellulose fibre.
  • the mineral wool and shredded paper comprise 90-96.67 % by weight of the dry composition.
  • the refracted clay material has been fired at or above a temperature of approximately 1815.5 °C (3300 °F) so as to have a melting point of 1510 °C (2750 °F).
  • the refracted clay material is in the form of particles and has a bulk density of 480.3 Kg/m3 (30 lbs per cubic foot) plus or minus 5 %.
  • the particles of the refracted clay material are embedded in the normally-flammable fibrous material to reduce the flammability thereof.
  • a surfactant can be added to the liquid sodium silicate to act as a wetting agent.
  • the surfactant is an anionic sulfonated alkyl ester comprising approximately 0.5 % by weight of the liquid adhesive.
  • the present invention is also directed to a method of making a lightweight soundproofing, insulating and fireproofing material.
  • the method includes the steps of providing a dry composition by providing 16.67-36.67 % by weight of an organic lightweight normally-flammable fibrous material, shredding the normally-flammable fibrous material, providing 3.33-10 % by weight of a refracted clay material and embedding the refracted clay material in the normally-flammable fibrous material after shredding to reduce the flammability thereof.
  • the method of providing the dry composition also includes the steps of providing 60-80 % by weight of an inorganic lightweight non-flammable fibrous material, pulling the non-flammable fibrous material apart to provide a high temperature loose fibre material, and mixing the non-flammable fibrous material with the normally-flammable fibrous material after the refracted clay has been embedded in the normally-flammable fibrous material and the non-flammable fibrous material has been pulled apart.
  • the method also includes the steps of providing a liquid adhesive by providing liquid sodium silicate having a ratio of silicon dioxide to sodium oxide that is greater than 3.22:1, mixing the liquid sodium silicate with water in a ratio of approximately 1:1, and adding a surfactant in the liquid sodium silicate to act as a wetting agent. With the lightweight soundproofing, insulating and fireproofing material so formed, the liquid adhesive is used with the dry composition at the rate of approximately 208.175 l (55 gallons) of liquid adhesive for each 135.9 Kg (300 lbs) of dry composition.
  • an inexpensive but highly effective lightweight soundproofing, insulating and fireproofing material for building purposes comprises a dry composition including 60-80 % by weight of an inorganic lightweight non-flammable fibrous material, 16.67-36.67 % by weight of an organic lightweight normally-flammable fibrous material, and 3.33-10 % by weight of a refracted clay material which reduces the flammability of the normally-flammable fibrous material.
  • the material comprises a liquid adhesive including a liquid sodium silicate having a ratio of silicon dioxide, commonly known as silica sand, to sodium oxide, commonly known as soda ash, that is greater in the final product than 3.22:1.
  • the non-flammable fibrous material includes mineral wool and the normally-flammable fibrous material includes cellulose fibre.
  • shredded paper is utilized to provide the cellulose fibre and, more particularly, the shredded paper suitably is a long fibre SBS polycoated sulfide paper which gives a desired white colour to the material after is has been applied to a surface.
  • the mineral wool and the shredded paper should comprise 90-96.67 % by weight of the dry product.
  • the mineral wool comprises a high temperature loose fibre material that is lightweight, non-burnable, non-meltable, and insulation heat protecting.
  • the melting point of the mineral wool is greater than 1148.8 °C (2100 °F).
  • the refracted clay material has been fired at or above a temperature of approximately 1815.5 °C (3300 °F) so as to have a melting point of 1510 °C (2750 °F).
  • the refracted clay material is in the form of particles and has a bulk density of 480.3 Kg/m3 (30 lbs per cubic feet) plus or minus 5 %.
  • the particles of refracted clay material are embedded in the normally-flammable fibrous material in order to reduce the flammability thereof.
  • the liquid sodium silicate comprises a fireproof adhesive adapted to retain the dry composition on a surface in a fireproof manner.
  • the liquid sodium silicate can be a solution of about 50 % water which can thereafter be further diluted by mixing with water in a ratio of approximately 1:1 after which it can be used with the dry composition at the rate of aproximately 208.18 l (55 gallons) of liquid adhesive for each 135.9 Kg (300 lbs) of dry composition.
  • a surfactant which is preferably an anionic sulfonated alkyl ester comprising approximately 0.5 % by weight of the liquid adhesive can be added to act as a wetting agent.
  • the material can be applied in a single coat on the order of 10.16 cm (four inches) thick. It will also remain flexible after curing, and it has been found that, with the combination of the dry composition and liquid adhesive, the adhesive, as specifically set forth herein and in marked contrast to present dry adhesive, will not melt even at 1148.8 °C (2100 °F) after the dry composition and liquid adhesive have been sprayed onto a surface. As a result, the material has been demonstrated to possess excellent insulation and fireproofing qualities.
  • the material is believed to be capable of passing a two hour fire rating at 1010°C (1850 °F) in accordance with the requirements of Underwriters Laboratories. It is also known that the material exhibits excellent soundproofing qualities and is extremely lightweight and that a 2.54 cm (one inch) thickness covering 9.29 m3 (100 square feet) weighs approximately only 13.6 Kg (30 lbs). Accordingly, the material is believed to be the first lightweight soundproofing, insulating and fireproofing material having commercial viability.
  • the refracted clay material of a type such as that sold under the trademark "KAOLITE AZ" by Babcock & Wilcox.
  • the liquid sodium silicate of a type such as that sold by Occidental Chemical Corporation, although any liquid sodium silicate within the parameters set forth herein will suffice.
  • the surfactant can be of a type such as that sold under the trademark "NOPCO” by Occidental Chemical Corporation.
  • the material By utilizing a high percentage of mineral wool, the material has an exceptional R value, excellent soundproofing qualities, and does not tend to burn away. It should also be noted that the refracted clay material, when embedded in the shredded paper, reduces its flammability to a tolerable level that does not impede the fireproofing characteristics of the material. Further, by using the surfactant, the liquid adhesive sticks better to the fibrous materials and the material is given greater flexibility after is cures.
  • a method of making a lightweight soundproofing, insulating and fireproofing material includes the steps of providing a dry composition by providing 16.67-37.67 % by weight of an organic lightweight normally-flammable fibrous material, shredding the normally-flammable fibrous material, providing 3.33-10 % by weight of a refracted clay material, and embedding the refracted clay material in the normally-flammable fibrous material after shredding to reduce the flammability thereof.
  • the method of providing the dry composition also includes the steps of providing 60-80 % by weight of an inorganic lightweight non-flammable fibrous material, pulling the non-flammable fibrous material apart to provide a high temperature loose fibre material, and mixing the non-flammable fibrous material with the normally-flammable fibrous material after the refracted clay material has been embedded in the normally-flammable fibrous material and the non-flammable fibrous material has been pulled apart.
  • the method also includes the steps of providing a liquid adhesive by providing liquid sodium silicate in a solution of about 50 % water and having a ratio of silicon dioxide, commonly known as silica sand, to sodium oxide, commonly known as soda ash, that is greater in the end product than 3.22:1, mixing the liquid sodium silicate with water in a ratio of approximately 1:1, after which the liquid adhesive can be used with the dry composition at the rate of approximately 208.18 l (55 gallons) of liquid adhesive for each 135.9 Kg (300 lbs) of dry composition.
  • the liquid adhesive is adapted to retain the dry composition on a surface in a fireproof manner.
  • the method may include the step of adding a surfactant to the liquid sodium silicate to act as a wetting agent.
  • the surfactant is an anionic sulfonated alkyl ester comprising approximately 0.5 % by weight of the liquid adhesive. In this manner, the liquid adhesive will stick better to the fibrous materials and the material will retain flexibility after curing.
